You might need to have your BCM(body control module) tested.If it is faulty it will normally cause these problems.

Rpm , gas , temp guage not working


All of these gauges are digital are controlled by a computer in the instrument cluster. You will need to remove the cluster and send it out for repair by a factory approved instrument cluster repair center. You can find these on line. JUst Goggle "Dodge Instrument Cluster repair"

Does the culster board control the gas indicator as will as the millege


Yes, the gas gauge works with the digital gas information on the cluster. So if your gauge is malfunctioning, your gas info in the digital cluster will be a misreading.

Gauges for 99 Pontiac Grand Am Not working right.


This is a ground problem. There are cluster grounds on the bolts that bolt the engine and trans together. You will have two of them one in the front under the front engine mounting bracket and one towards the back of the car almost right under the EGR. This is a common problem and requires a quite a bit of time to get to the two bolts to clean the connections on the grounding clusters. I ran into this problem after replacing my engine and it took me several hours before I finally found this problem. Good luck!
